We've been working for a while in mesh generation & adaptation to openFoam fvMesh structure; Right now, we have a compact set of points and cells ready to be loaded into a fvMesh, but the problem is detecting the "faces" needed for the constructor. Does anyone knows if there's any openFoam function that can help us with that job?

The thing is that right now I have the mesh info in memory (only info about points and cell shapes) but no "face" connectivity info; The mesh is made up of tets and voxels, and I've been looking inside the netgen neutral and ccm24 converters to see how do they obtain the face connectivity info. time is precious here, so writing it to another existant format is almost unthinkable, because that's exactly the kind of operations we're trying to minimize.
